Deep Sea Drilling Project


Published 1974


Description: This film depicts the work of D/V Glomar Challenger on the NSF sponsored Deep Sea Drilling Project. The film includes footage of drilling operations and cores and describes the theory of sea floor spreading. The D/V Glomar Challenger (ship) mission was the coring of deep ocean sediments in waters of twenty thousand deep in the oceans of the world. The mission was broken up into cruises or legs, each lasting about two months. Film shows ship activity, the computer that was used, radio receiving satellite signals from space to locate exact position wanted. Shows graphic demonstration of a giant land mass which breaks up into several continents. Also scientists show bones of animals found on one continent from another, demonstrating that the continents were together at one time. As a result why did the continents divide? Gives explanation of deep floor spreading of the ocean floors, where earth’s magnetic fields caused the ridges to move outward. Scientists wanted to prove the magnetic pulls in the rocks, showing opposite pulls could be determined by the cores they would pull from the ocean bottom floor. Film shows the drilling, also the geologist and other scientists working on the ship.
